If ab+bc+ac=0, calculate a^2/(a^2+2bc)+b^2/(b^2+2ac)+c^2/(c^2+2ab)

If (a+b+c)^2=a^2+b^2+c^2, calculate a^2/(a^2+2bc)+b^2/(b^2+2ac)+c^2/(c^2+2ab). The key for the calculation is to preserve pieces that are symmetric among a, b, and c.

Bro, in school these lines were alien to me. They still are to this day. I just can't fucking understand how your brains work
